BOILER FQR CLEANING OR BOILING RAGS.

SPECIFICATION forming part of Letters Patent No. 395,416, dated January 1, 1889.

Application filed February 6, 1883. Serial No. 263,134. (No model.)

To (L-ZZ whom it may concern:

Be it known that. I, GEORGE F. BARToN, a citizen of the United States, residing at Varehouse Point, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Boilers for Cleaning or Boiling Bags, of which the following is a specification.

My invention relates to improvements in boilers for boiling or cleaning rags; and the chief object of my invention is to more rapidly draw off the steam and water preparatory to removing the rags and refilling the boiler.

In the accompanying drawings, Figure 1 is a longitudinal section, partly in elevation, of a boiler containing my improvement. Fig. 2 is an. enlarged transverse sectionot the same, partly in elevation, the plane of section being indicated by the line 1: :r, Fig. 1. Fig. 3 is a detached view showin in plan. view the strainer which covers the exit and adjacent parts, and Fig. et. is a central section, longitudinally of the boiler, of the ejector, the same being on a still larger scale.

A designates a cylindrical boiler mounted upon hollow axles, throi'lgh which steam is admitted by the pipes a, the ends of the stoann pipes being protected by the strainers Z). The boiler is also provided. with man-holes or openings c, which are provided with suitable covers, said holes being used for the insertion and removal of rags.

d des'igl'iates a discharge cock or valve on one side of the boiler, the opening leading therefrom into the boilerbeing prote -tcd by means ol the hinged screen or strainer f. The parts so lar specifically described are all of them old and in common use. Instez'u'l oi a simple openingleading to the disellarge-mick, I provide said opening with. an ejector. In the prelj'errod [form of, construction I secure a plate, g, to the under side of the boiler, which plate internally threaded at its smallest diameter to receive the end of the pipe leading to the outlet-valved or the threaded neck forming a part of said valve. The larger internal diameter of said plate :is threadwfl to receive the bushing 72, Fig. .4, to which bushing the ejector-nozzle 7c is secured, said ejectornozzle being preferably formed in one and the same piece with the bushing 71. From the ejector-nozzle 70 there is a pipe, m, which 6X- tends circumferentially about half way around the boiler on the inside and is provided with perforations toward its end, as shown. The strainer f, in prior boilers, is provided with hinges, so that it may be turned back from over the exit when desired, and in order to accommodate the pipe in to this hinged strainer or screen, I form an elbow near the front end of the pipe 77?, whereby said pipe first extends laterally in a line parallel to the hinge or hinges of the strainer and then circumferentially to the opposite side of the boiler, as shown. The boiler is filled and the rags boiled or steamed in the ordinary manner, so that when the rags are thoroughly sat urated they will fill the boiler only about half full. The stop-cock (Z is closed and the boiler given a rotary motion in the direction indicated by the arrow in Fig. 2, so that the rags will not catch under the perforated end of the pipe m. After the rags have been sufficiently boiled or steamed the rotation of the boiler is stopped, steam cut oft from the inlet-pipes (i (i, and any suitable conduit is connected to the lower end of the stop-cock (Z to carry the steam and water to any desired point. The stop-cock d is then opened, when the steam, which the rags and water confine principally to the upper part of the boiler, will enter the perforations at the endoi the pipem and pass out through the ejector-nozzle 71: with all the force due to the pressure of the steam within the boiler. The steam thus finds ready exit and in addition thereto it acts as in an ordinary ejector to draw with it the water from the boiler, so that the steam and water are both discharged in a much less time than in the boilers as heretofore constructed, and more water is drawn from the rags than would natu rally flow out without the use of the ejector. After the steam and water are thus drawn off the man-holes can be opened for removing the rags and refilling the boiler for a subsequent operati on.

I claim as my invention- 1. The combination of a boiler of the class described, with the ejector at the dischargeopening of the boiler, and the pipe 12?, extending around to the opposite side of the boiler, substantially as described, and for the purpose specified.

2. In a boiler of the class described, the combination of an ejector, the covering screen or strainerf, hinged as described, an d the pipe m, leading laterally to one side of the strainer in a line parallel to its hinge and from thence to the opposite side oi the boiler, substantially 10 as described, and for the purpose specified.

3. The combination of a boiler of the class described and the pipe m, extending from under the screen at theexit around to the opposite side of the boiler, substantially as described, and for the purpose specified.
